Nearly 90 years after Ugo Cerletti and Lucio Bini introduced electroconvulsive therapy (ECT), brain stimulation therapies such as ECT and repetitive transcranial magnetic stimulation (rTMS) have become commonplace in psychiatry because they are highly effective in treating depression and schizophrenia, but their cellular mechanisms remain poorly understood. The research team introduced REPOPS, a type of patterned stimulation in mice designed to mimic key features of ECT-like neuron activation. Mice receiving REPOPS showed increased locomotor activity and decreased depression-like behavior, revealing stimulus-induced sustained behavioral changes similar to an ECT-like state. At the cellular level, this stimulus induced a cytodegenerative state, and…
Chronic hepatitis B virus (HBV) infection remains a major cause of liver disease worldwide, causing progressive necroinflammation and often ultimately leading to cirrhosis and hepatocellular carcinoma. Despite the clinical importance of this chronic inflammatory state, the precise molecular mechanisms that initiate and maintain HBV-induced liver damage remain poorly understood. Recently genes and diseases In this study, researchers from Chongqing Medical University investigated the mechanisms underlying HBV-induced hepatitis and identified a reactive oxygen species (ROS)-dependent signaling cascade that activates the Jak2/Stat3 pathway, thereby triggering the hepatitis response.Transcriptome analysis of liver samples from HBV transgenic mice and chronic HBV-infected patients revealed that…
Professor Yasutoshi Kido of the Osaka Metropolitan University Graduate School of Medicine is collaborating with Danaform Inc. and the National Institute of Biomedical Research of the Democratic Republic of the Congo (INRB) to develop a portable rapid diagnostic system for Ebola virus disease (EVD) caused by Bundibugyo virus (BDBV). This project was selected for funding from the Global Health Innovative Technology Fund (GHIT Fund). The World Health Organization (WHO) declared on May 16, 2026 (Geneva time, May 17 Japan time) a “Public Health Emergency of International Concern” (PHEIC) regarding the Ebola outbreak caused by BDBV in the Democratic Republic of…
Terraforming is the process of reshaping planets and moons so that they can support humans and other Earth-like life forms. In theory, that means making an otherworld’s atmosphere, climate, and surface more similar to Earth’s by adding oxygen, creating a stable mass of liquid water, and creating temperatures suitable for life. Mars has long been considered a top candidate, with proposals ranging from releasing greenhouse gases to warm the planet to using microbes that can slowly produce oxygen over centuries. For decades, the concept of terraforming Mars existed primarily in the world of science fiction. The vision of turning a…
Almost everyone interested in public health agrees that it is a good idea to help people quit smoking, the number one cause of preventable death in the United States. Physicians may soon have further encouragement to step up thanks to proposed changes to Medicare’s physician fee schedule.Physicians who provide counseling on smoking cessation of cigarettes and other tobacco products during patient visits will receive a 19% increase in reimbursement, according to several paragraphs embedded in a 1,592-page document released this week. The same adjustments apply to alcohol and drug abuse assessment and intervention during physician visits.“Given the evidence supporting the…
Recent research published in quarterly public opinion This provides evidence that the public has deeply divided beliefs about the economic impact of artificial intelligence. This study suggests that these differing opinions tend to align with existing political divisions in North America. This finding shows that politicians can easily exploit these divisions to turn technology policy into a highly polarized political issue. The research team included Sophie Bowin, Beatriz Magistro, R. Michael Alvarez, Bart Bonikowski, and Peter J. Loewen. These authors represent universities in the United States and Canada, including the University of British Columbia, Northeastern University, California Institute of Technology,…
Laser-based technology being developed at the University of Adelaide could soon allow authorities to detect dangerous counterfeit alcohol, expose wine fraud and even identify dangerous chemicals in sealed bottles without ever opening them. The breakthrough builds on newly published research carried out at the University of St Andrews in Scotland in collaboration with the University of Adelaide, which demonstrated that a specially designed laser system could detect toxic methanol hidden inside unopened spirits bottles, even through tinted glass. While the latest research focuses on identifying dangerous methanol contamination in whiskey and other spirits, University of Adelaide researchers are already extending…
When you combine disruptions in daily life with a history of childhood trauma, you can accurately predict which teens are at the greatest risk of developing both depression and anxiety. By examining teenagers’ internal biological rhythms, along with their past experiences, medical professionals may be able to better identify those in need of early mental health intervention. The study results were published in the journal Psychiatry Research. The mental health of young people has worsened globally over the past few decades. The majority of mental disorders begin before a person reaches their mid-20s. Although emotional hurdles during adolescence may be…
ATLANTA — Federal health officials have identified Mexican lettuce served at Taco Bell stores across five U.S. states as a widespread source of the diarrhea-causing parasite Cyclospora. The U.S. Centers for Disease Control and Prevention late Thursday warned consumers not to eat shredded iceberg lettuce from Taco Bell restaurants in Indiana, Kentucky, Michigan, Ohio and West Virginia. A record number of Cyclospora cases have been reported in more than 30 states, and experts say not all recent U.S. illnesses are caused by a single source. The Food and Drug Administration’s investigation identified one supplier of lettuce. The company was not…
A new study using Mongolian gerbils as an animal model demonstrates for the first time that transtympanic infrared laser stimulation of the cochlea elicits reliable auditory-guided behavior in awake animals without the need for genetic modification or invasive surgical implantation. The research was led by Dr. Yuta Tamai, a researcher at Doshisha University’s Acoustic Navigation Research Center (also a Japan Society for the Promotion of Science Research Fellow at Keio University and a researcher at Eberhard Karls University Tübingen), Professor Kohta I. Kobayasi of the University’s Faculty of Biomedical Sciences, and Associate Professor Koji Toda of the Keio University Department…
